Bought this today at a "mom and pop" hardware store. At $13, I thought the price was quite reasonable.
Searches for it lead me to believe the company is no longer in business though.

It has an alarm built in that detects movement a certain number of times and then sounds a 110 decimal alarm. Resets itself etc.
It uses 9 LR44 batteries which last around 2 years.
I think it is closer to 90 - 100 decibels.
What do you think?

Adding an alarm to a bad lock does not magically make it a good and
secure lock.

The "lock picking lawyer" is quite good at picking, bypassing, and
destructive entry.

Duh. I just noticed another problem. The pot metal lock case does a
fairly good job of blocking the high frequency beeper sounds. So,
holes in the lock case are needed to make the beeper heard. All that
is necessary to silence the beeping is plug up the holes with putty or
wrap the holes with a towel. It could be beeping away merrily and
nobody would hear it while I pick the lock.
